Question

我收到一个错误：当我在浏览器中查看应用程序时，ActiveRecord :: ConnectionNotEstablished（下面的完整跟踪）。我似乎无法弄清楚如何解决这个问题。我尝试了下面提到的项目：

此处http://www.benjaminoakes.com/2011/09/15/activerecordconnectionnotestablished-in-rails-3-1-on-heroku/

以及此处stackoverflow.com/questions/7871233/ruby-activerecordconnectionnotestablished

和www.ruby-forum.com/topic/2854331

和其他多个人

（仅供参考，我在Windows 7上运行，Ruby 1.9.3，没有RVM）我的代码在此处提供：https://github.com/justjoehere/sample_app

非常感谢任何帮助

我的Gemfile

source 'https://rubygems.org'
gem 'rails', '3.2.13'
group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.9.0'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails', '3.2.4'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.2.1'
group :test do
  gem 'capybara', '1.1.2'
end
group :production do
  gem 'pg', '0.12.2'
end

数据库yaml文件
